Number and Number Relations: Lesson 3

Visual models support young mathematicians as they deepen their fractional number sense in this elementary math lesson. Using fraction circle manipulatives, children explore basic unit fractions as they develop the fundamental...

Pattern recognition is an essential step in the development of young mathematicians fluency with the four basic operations. This simple skills practice instructional activity asks children identify and complete three different numerical...

Need a number line? Here are four number lines ranging from zero to twenty.

Third graders construct numbers to the millions place. In this 30-page place value lesson, learners create numbers and evaluate the place value of digits. They explore standard and expanded form of numbers. An incredible resource!

This short problem with representing fractions on a number line is more than meets the eye. Labeled only with the numbers zero and 1/4, a number line is used to locate the fraction 2/3. A solution can be found in multiple ways, but young...

Understanding place value is a basic mathematics skill. This Khan Academy video shows students how to write the number 14,897 in the expanded form. He explains that the 7 in the ones place is the same as 7x1, the 9 in the tens place is...

Using a number line can provide students with a concrete representation of the value various numbers hold. Sal plots 6 different numbers on a number line. He includes whole, decimal, and negative numbers.

The second of eight videos on rounding whole numbers to the nearest 10 or 100 describes how to use a number line to create benchmark numbers. A review of place value and counting by 10s starts off the lesson, followed by a discussion on...

Explicit and direct instruction is great for children who are struggling in math; it is also great for introducing a new topic or idea. Help your learners understand exactly what it means to identify an equivalent fraction on a number...

Step by step, two examples of creating number lines are explained through a series of animations. One is meant to watch at home, the second can be viewed in class, and there is a third tab with two sample problems to try. This skill,...
